Abstract:

We present first results of a survey being made in a broad-band 6.75 micron filter using the ISOCAM infrared camera in its parallel mode at ~6" resolution. So far we have analysed a sky area of ~1.375 deg 2 down to a limiting flux of 5 mJy and detected a total of 287 objects. The final survey will cover a sky area of ~33 deg2, most of which will be done in staring mode, to which we have restricted ourselves in the present paper. The final catalogue should reach a typical sensitivity limit of ~1 mJy. We estimate that at the detection limit 99% of the objects will have a galactic origin.
